Then she had yet another son, whom she named Shelah. She gave birth to him in Kezib.

Judah recognized them and said, “She is more upright than I am, because I wouldn’t give her to Shelah my son.” He did not have sexual relations with her again.

The sons of Judah: Er, Onan, Shelah, Perez, and Zerah (but Er and Onan died in the land of Canaan). The sons of Perez were Hezron and Hamul.

And the Judahites by their families were: from Shelah, the family of the Shelahites; from Perez, the family of the Perezites; and from Zerah, the family of the Zerahites.

The sons of Shelah son of Judah: Er the father of Lecah, Laadah the father of Mareshah, the clans of the linen workers at Beth-Ashbea,

Then Judah said to his daughter-in-law Tamar, “Live as a widow in your father’s house until Shelah my son grows up.” For he thought, “I don’t want him to die like his brothers.” So Tamar went and lived in her father’s house.

So she removed her widow’s clothes and covered herself with a veil. She wrapped herself and sat at the entrance to Enaim which is on the way to Timnah. (She did this because she saw that she had not been given to Shelah as a wife, even though he had now grown up.)

The sons of Judah: Er, Onan, and Shelah. These three were born to him by Bathshua, a Canaanite woman. Er, Judah’s firstborn, displeased the Lord, so the Lord killed him.
